How to Password Protect a USB Drive

Although USB drives are considered safer than cloud data storage platforms, your data will be at risk if not protected with a password. 

There are several simple ways to secure your USB drive using the encryption feature. Follow our easy guide on how to protect a flash drive with a password. 

How to Password Protect a USB Drive 

Here are some useful software and app recommendations to protect your USB drive. 

BitLocker 

BitLocker is a free built-in encryption feature on Windows. It is easy to use and available on earlier versions of Windows as well. 

1. Connect your USB to your computer.
2. Hit right-click on your USB drive and from the menu, choose Turn on BitLocker. 
   
3. Click on Use a password to unlock the drive and enter your new password. Click on Next. 
   
4. BitLocker will ask you to choose one of the ways to save your password. Click on Save to your Microsoft account. 
   
5. Now, you’ll get to choose how much content of your drive you want to encrypt. Choose Encrypt the entire drive and click on Next. 
6. On the next page, you can pick one of the encryption modes. We recommend selecting Compatible mode if you use your USB on other devices often. Click on Next. 
7. Click on Start Encrypting. 
   

After the process ends, your drive becomes secure with a password. Doing this method once is enough as your drive will always remain safe even when you add new data to it. 

This is a suitable, accessible option if you don’t want to install third-party apps. 

Rohos Mini Drive

Rohos Mini Drive is a free software that uses automatic encryption with AES 256-bit key length. It allows you to easily encrypt or hide your data on your USB drive by adding an encrypted drive. 

So, you can use non-sensitive data without worrying and access encrypted data only when needed. Another cool feature about this software is that you do not need administrator rights to run it. Here’s how you can use the Rohos Mini Drive to protect your USB drive.

1. Connect your USB drive to your computer.
2. Open Rohos Mini Drive and click on Encrypt USB drive. 
   
3. Now, you can choose a new password to encrypt and click on Create disk. 
   
4. The encryption process will now begin and you can see it on a pop-up box. After it’s done, you’ll get a completion message.
5. Now, open your File Explorer and in the list of drives, you can see a new drive called, Encrypted Disk. This is a separate drive, so it won’t be located inside your USB drive. 
   
6. Now, you can transfer your desired files to the new encrypted disk. 
7. If you remove the USB from your computer, the encrypted drive will also be removed together. 

Later, when you reconnect your USB drive and open your encrypted files, go to the Rohos Mini executable file. Enter your password, and you’ll get access to your files.

VeraCrypt

VeraCrypt is another decent app by Idrix and is available on Windows, MacOS, and Linux. Although it requires admin rights, it’s easy to use since it directly operates from your USB drive. This app uses various encryption algorithms, like AES 256-bit, Serpent, TwoFish, and more. 

With VeraCrypt, you can get an independent encrypted disk. It’s best to note that you can only encrypt data of 2GB size. If you need more, you can get its premium version. 

Here’s how you can use VeraCrypt:

1. Open the app and you’ll see the list of drives. Select one and click on Create Volume. It will open the VeraCrypt Volume Creation Wizard. 
2. If you want to encrypt your whole drive, choose Encrypt a non-system partition and click on Next. 
   
3. Now, you can pick either Standard or Hidden VeraCrypt volume. If you pick the hidden volume, it will be safer, but you’ll need to format the USB drive. So, click on Standard and click on Select Device. 
4. Select your USB disk and click on OK and then Next. 
   
5. Click on Encrypt partition in place and click on Next. 
6. Click on Encryption and Hash Algorithm. Click on Next and set your desired volume size, and again click on Next. 
   
7. Set a new Volume Password and click on Next. 
   
8. Move your mouse around until the bar color turns green, and click on Format.
